Diagnostic Steps

Solution

1. Preparation

Tools Required: Tire pressure gauge, air compressor, OBD-II scanner, jack, jack stands, tire repair kit (if needed).
Ensure the vehicle is parked on a level surface and the engine is off.

2. Check and Adjust Tire Pressure

Sub-steps:
1. Remove valve caps from each tire.
2. Use the tire pressure gauge to check the pressure of each tire.
3. Compare the readings to the manufacturer's recommended tire pressure (found on the driver’s door jamb).
4. Inflate any under-inflated tires using an air compressor to the correct pressure.
5. Replace the valve caps securely.

3. Inspect Tires for Damage

Sub-steps:
1. Visually inspect each tire for cuts, punctures, or other damage.
2. If a puncture is found, use a tire repair kit to seal small punctures or take the tire to a professional for repair if the damage is severe.
3. Check the tread depth; replace tires if tread is below the legal limit.

4. Reset the TPMS

Sub-steps:
1. Turn the ignition to the "ON" position without starting the engine.
2. Press and hold the TPMS reset button (usually located under the steering column or in the glove compartment) until the TPMS light blinks three times.
3. Start the vehicle and allow a few minutes for the system to recalibrate.
